Operation Elveden

Elveden launched after police were handed documents suggesting News International journalists had made illegal payments to officers

Documents were handed over by News International on 20 June 2010

Investigation is being supervised by the Independent Police Complaints Commission

A total of 26 arrests have so far been made as part of Operation Elveden

Police said a 36-year-old man was arrested at his home in Kent on suspicion of conspiracy to corrupt.

Officers arrested the former serviceman on suspicion of misconduct in a public office, and a 38-year-old woman on suspicion of aiding and abetting misconduct in a public office, at their Lancashire home.

The arrests were made at about 06:00 BST on Thursday.

Rupert Murdoch's News Corporation set up a management standards committee (MSC) last July to carry out internal investigations of its newspapers following the phone-hacking scandal.

News International - the UK division of News Corp - confirmed that a Sun journalist had been arrested.

The Crown Prosecution Service confirmed on Wednesday that it had received the first batch of files from officers relating to Operation Elveden and Operation Weeting - the Metropolitan Police's continuing phone-hacking investigation to which it is linked.

The documents have now been handed to Director of Public Prosecutions Keir Starmer QC for him to decide whether to bring charges.

The management standards committee is working with detectives to look at whether journalists at Mr Murdoch's UK papers - The Sun, The Times and The Sunday Times - have been involved in corrupt payments to police and other public servants.

The News of the World - another of Mr Murdoch's publications - was forced to close in July 2011, after it was revealed that the voicemail messages of a string of public figures and celebrities had been hacked into.
